Apple today started offering refurbished 13" MacBook Pro with Retina Display models on their website. This includes the base model with a 2.5GHz dual-core Intel Core i5 processor, 8GB of RAM, 128GB solid-state drive, and Intel HD 4000 graphics for $1439. As well as the upper model with a 256GB solid-state drive for $1699, and a model with the 2.9GHz dual-core Intel Core i7 and 512GB solid-state drive for $2289. All of the models are covered by Apple's One-Year Limited Warranty and include free shipping.

It should also be noted that Apple began offering refurbished 15" MacBook Pro with Retina Display models earlier this month.

The Canadian website is 99% the same as the US site. I compared the sites last night. Almost all of the choices were identical. I did however see one unit on the US site that was not listed on the Canadian site. So it may work in favor of Canada once in a while as well.

I've noticed updates primarily on Wednesdays.

You can get apps that notify you of updates. I can't remember the name of the app. But a quick search will get you there.

There are other Mac sites with discounts on the 2012 models i saw.When do you think this 2013 model is coming out?

This will sound snarky, not my intention, but that doesn't make it any less true: when Apple wishes it to be released. There won't be anybody on any forum that can say with 100% accuracy, even with leaks, when exactly or what exactly will be released._________________2.3 GHz i7 Mini (stock)

I don't see new iMac or Mac minis coming out with Haswell until later in 2013. Which probably won't be a big deal for either machine. I also think the basic design and port selection will remain the same. So, I really see no need in putting off buying one if you need a new machine. Especially if you can get in on a warrantied refurb for around five bills._________________My Setup
